1770 MPa High-Tensile Prestressing Wire for Flexible Solar Mounting Systems
The Rise of Flexible Solar Mounting Systems
As solar energy projects expand into complex terrains—such as mountainous areas, fisheries, wastewater treatment zones, and agricultural land—traditional ground-mounted structures are becoming less efficient.
Flexible solar mounting systems (also known as suspension PV structures) use high-tension steel wire or cables to span long distances and suspend photovoltaic panels.
Compared with conventional systems, this approach offers several advantages:
- Reduced steel consumption
- Lower foundation requirements
- Adaptability to uneven terrain
However, the performance and safety of these systems depend heavily on one critical material: high-tensile steel wire.
Why 1770 MPa Steel Wire is Ideal for Solar Suspension Systems
Flexible PV structures require materials that can withstand constant tensile stress, wind loads, and environmental exposure over long periods.
1770 MPa high-tensile steel wire provides an effective balance between strength, weight, and cost.
Key Advantages
- High Strength Capacity
A 3.0 mm wire can achieve up to 12.5 kN breaking force (lab-tested), making it suitable for tension applications. - Optimized Diameter-to-Strength Ratio
Smaller diameter reduces overall system weight while maintaining structural performance. - Efficient Installation
Suitable for long-span applications with fewer connection points.

Why Coil Delivery Matters
For flexible solar mounting systems, installation efficiency and structural integrity are critical.
Coiled steel wire offers several practical advantages:
- Maintains original mechanical properties
- Avoids micro-damage caused by straightening
- Enables continuous installation across long spans
- Reduces connection points and potential failure risks
For EPC contractors and installers, this means faster deployment and improved reliability.
Corrosion Resistance for Long-Term Solar Projects
Solar installations are long-term investments exposed to outdoor environments for 20–25 years.
This steel wire is coated with Galfan (Zn-Al alloy) at 250 g/m², providing enhanced corrosion resistance.
Key benefits include:
- Better performance in humid and coastal environments
- Improved durability compared to standard zinc coatings
- Extended service life aligned with solar project requirements
Typical Applications
This type of high-tensile steel wire is widely used in:
- Flexible solar mounting systems
- Suspension photovoltaic structures
- Agricultural solar installations
- Lightweight cable-supported structures
Supply Capability
We provide export-ready high-tensile steel wire solutions for global buyers, including traders and solar structure manufacturers.
Our supply capability includes:
- Stable sourcing under GB/T 17101 standard
- Coil packaging suitable for container transportation
- Flexible cooperation for bulk orders
- Third-party inspection support (SGS, BV, etc.)
FAQ
Q1:What span can 3.0 mm 1770 MPa steel wire support?
A:The achievable span depends on system design, load conditions, and safety factors. Engineers typically determine working load based on standard safety coefficients and project requirements.
Q2:Why use steel wire instead of steel strand?
A:Steel wire is generally more cost-effective and easier to handle. It is suitable for lightweight flexible systems, while steel strand is typically used for heavier structural applications.
Q3:Is Galfan better than traditional zinc coating?
A:Yes. Galfan coating provides better corrosion resistance and longer service life, especially in outdoor and humid environments.
Q4:Can you provide custom lengths?
A:Currently, the product is supplied in coil form, which is more suitable for long-span installation and transportation efficiency.
Q5:Do you support third-party inspection?
A:Yes, third-party inspections such as SGS or BV can be arranged before shipment.
